I have a following code below:

              kg=N[Sqrt[2/Log[2]] Pi];
              width=-1 ( Ceiling[1/(2 bt)]);
              duration=(-2 width)+1;
        p[t_]:=( Erf[-1 kgfilterb (t-bitperiod/2)]+
                 Erf[kg filterb(t+bitperiod/2)])/(bitperiod \ 4);
        qfunc=Table[NIntegrate[p[t],{t,width,k}],{k,width,-1 width,.1}];
               q[t_]:=gaussq[t]/;0<=t<=(-2 width);
               q[t_]:=.5/;t>(-2 width)

I have very newbie quesiton ....
how/when is the q[t_] called?
i mean, if i write stg like this 

  x = makegaussianq[0.38, 10]

what would this fuction return.
would it return q[t] to x ?

basically how do i read the above code?

my background is basically in C and C++ coding and i am finding it 
difficult to read the above code.
